This book was released on 2005 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beluga whales (Delphinapterus leucas) occur throughout the Canadian Arctic and in the Saint Lawrence River estuary. The beluga populations of Cumberland Sound, Eastern Hudson Bay, Ungava Bay and Saint Lawrence River Estuary are considered endangered. This document describes the characteristics of a recovered beluga population, discusses considerations in selecting recovery times, and provides information on species biology. It then provides a recovery potential assessment for each of the endangered populations.

This book was released on 2005 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the peer review meeting summarized in this report was to proceed with a recovery potential assessment for 4 beluga populations designated as at risk under the Species at Risk Act (SARA). The 4 beluga populations are the Cumberland Sound, the Saint Lawrence Estuary, the Ungava Bay and the Eastern Hudson Bay populations. The 1st part of the meeting focussed on the development of interim descriptions of the biological properties of suitable recovery targets and recovery times that could be applied to beluga populations of concern. The 2nd part of the meeting addressed the recovery potential assessment for each beluga population.

Available in PDF, EPUB and Kindle. Book excerpt: This document reviews the current state of knowledge about St. Lawrence belugas, recommends a series of actions for ensuring their survival and proposes an implementation schedule. The goal of the Recovery Plan is to bring population numbers and conditions to a state where natural event and human activities will not threaten the survival of the St. Lawrence beluga whale population. A subsidiary goal is to improve the status from endangered to vulnerable, as defined by COSEWIC.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beluga whales (Delphinapterus leucas) are an Arctic cetacean with circumpolar distribution. They are known to have distinct, lengthy and consistent migration paths to and from summer and wintering grounds. The Western Hudson Bay beluga population, the largest summering aggregation in the world, inhabits three main estuaries in the summer season. Little protection is afforded to them here, and little is known of the specific details of their summer distribution and factors affecting that distribution. Using a combination of satellite telemetry, aerial photos, satellite data, and visual observations and historical reports, investigations into factors affecting beluga distribution in Western Hudson Bay were conducted. An examination into beluga age class distribution near the Churchill and Seal River estuaries, using aerial survey imagery, suggested that belugas may not be segregating by age in summer, however the Seal River estuary may be more important from a calf-rearing perspective. Belugas use a greater home range than we would expect, based on historical range data, in the face of predation by their main predator, the killer whale (Orcinus orca). Killer whales are sighted more frequently in Hudson Bay than historically, and results presented here show that ice entrapments, occurring with higher frequency in the future, may impact distribution of beluga as killer whales expand their range and occurrence in Hudson Bay. Finally, an assessment of beluga behaviour in the presence of whale-watching vessels showed that beluga response to vessels varied but the probability of travelling behaviour was significantly greater with distance from vessels; belugas also appear to be spending more time interacting with vessels now, as compared to 15 years ago when there were fewer whale-watching vessels. The results found through this research are useful in informing climate change implications, marine-protected area boundaries, policy and marine spatial planning, and subsistence harvest management.

This book was released on 2012 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The St. Lawrence Estuary beluga population was listed as threatened under SARA in May 2005. In 1986, Fisheries and Oceans Canada set up the Ad Hoc Committee for the conservation of the St. Lawrence beluga, the objectives of which were to identify factors that threatened the population's survival and to make recommendations to favour its recovery. This project was carried out jointly by Fisheries and Oceans Canada and Environment Canada from 1988 to 1993 as part of the St. Lawrence Action Plan (SLAP), with the following objectives: to minimize disturbance to the beluga population, to combat the discharge and spread of toxic chemical products, and to conduct further research on the beluga. A fourth objective was added in 1989: to facilitate public access to information in order to raise awareness in Canada and Quebec of the St. Lawrence beluga. This document includes information about recovery and background of the beluga whale in the St. Lawrence Estuary.--Includes text from document.

Download or read book Conservation Value to Assisting Live stranded Neonates and Entrapped Juvenile Beluga Delphinapterus Leucas from the St Lawrence Estuary Population written by Michael O. Hammill and published by . This book was released on 2019 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The potential benefits of relocating live stranded or entrapped beluga to recovery of the St. Lawrence Estuary (SLE) beluga population were examined using a demographic model. The population is currently declining and information on reproduction rates are lacking. It is not possible to determine if the current decline is due to low reproductive rates, elevated mortality among neonates, or both. Adult survival is already quite high and there is unlikely much room for further improvement. Efforts to improve survival of neonates and juveniles are most likely to benefit population recovery. However, considerable numbers of animals must be assisted and successfully relocated each year to improve survival and halt the decline in population trend. Reports of live-stranded neonates or entrapped juveniles are infrequent. Therefore, the benefit of relocating these few individuals to population recovery is nil, and does not meet the objectives of Conservation Translocation. The occurrences of entrapped juveniles are rare, but if in good health these animals are more likely to survive when relocated compared to abandoned neonates. From a conservation perspective, the benefit of relocating entrapped juveniles to the population as a whole is likely nil given the rarity of these events. However, relocating these individuals may be considered on other grounds. Some of the factors that need to be considered have been identified (e.g. DFO Release and Rehabilitation Criteria)"--Abstract, p. iii.
